Does Samsung tcon board fit Toshiba TV?

Yes, replace the tcon board, good chance it will fix it.

Remove and clean the 2 flat ribbon cables going from the tcon to main board to the panel boards and see if that corrects the issue, next would be replace the tcon board if your set has one, if not the main

OMG..why so many bad answers on here all a sudden ...Chances are you have a bad Tcon board or its possible it could be the main as well however tcons fail way more than main boards with your issue, vertical lines means bad tcon, horizontal can mean a bad display...I can count on one hand the times Ive had a bad display with vertical lines and Ive serviced thousands of HD TV's over the years...but what I want you to do 1st is remove the LVDS cable that goes from the main board to the tcon board, clean the contacts and replace it...then do the same to the two flat panel ribbons that go from the tcon board to the panel, its not real common but on occasion they will loose connection and give vertical lines, don't want you to buy a board if cleaning the cable connections will help...just use a little rubbing alcohol to clean them...Good luck, if you need more help feel free to message me back.

The TCON board or the LCD panel is Faulty. Can confirm by replacing the TCON board.

My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display issue (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further updates will be on my Facebook page.

It can be T-CON board, ribbon cables between the T-CON board and the LCD panel.

hi:
this problem may be due to a faulty T-Con board, replace the board and the issue should be resolved.

Clean the connectors from the main to the Tcon along with the flat cables that go to the panel, next would be repalce the tcon board,if that doesn't fix it you may have a bad panel
